Summary
Researchers identified key genetic mutations in breast and colorectal cancers. This study reveals new cancer-related genes, offering potential diagnostic and therapeutic targets for these common diseases.
Area of Science:
- Genomics
- Cancer Biology
- Molecular Oncology
Background:
- The human genome project enables detailed identification of genetic alterations in cancer.
- Understanding these alterations is crucial for cancer research and treatment.
Purpose of the Study:
- To systematically analyze genetic alterations in common human cancers.
- To identify frequently mutated genes contributing to the neoplastic process.
Main Methods:
- Sequencing of well-annotated human protein-coding genes.
- Analysis of 13,023 genes across 11 breast and 11 colorectal cancer samples.
Main Results:
- Individual tumors accumulate an average of 90 mutant genes.
- 189 genes (average 11 per tumor) were identified as significantly mutated.
- Most identified genes were previously unknown in cancer and affect diverse cellular functions.
Conclusions:
- The study defines the genetic landscape of breast and colorectal cancers.
- Identified genes represent novel targets for cancer diagnostics and therapeutics.
- Findings open new research directions in tumor biology.

Multi-species Conserved Sequences
Next-generation sequencing technologies have created large genomic databases of a variety of animals and plants. Ever since the human genome project was completed, scientists studied the genome of primates, mammals, and other phylogenetically distant living beings. Such large-scale studies have provided new insights into the evolutionary relationship between organisms.
Although the genome of each species varies greatly from each other, a few sequences are highly conserved. Such conserved DNA...

Cancer-Critical Genes II: Tumor Suppressor Genes
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

Signal Sequences and Sorting Receptors
Signal sequences are short amino acid sequences that guide newly synthesized proteins to their proper location within the cell. Classical signal sequences are fifteen to sixty amino acids long and present at the N-terminus of a polypeptide chain. Each signal sequence has a conserved segment of basic residues towards their N terminus, a hydrophobic core, and a C-terminus rich in polar residues. The C-terminus also contains a signal cleavage site and features a -3 -1 sequence motif. The -3-1...
